its file extension.</p></li>

identifies the element with ID attribute value 'chapter1' of the
external XML resource 'http://example.com/bar.xml', provided as an
octet stream. Again, for the sake of interoperability, the element
identified as 'chapter1' should be obtained using an XPath transform
rather than a URI fragment (barename XPointer resolution in external
resources is not REQUIRED in this specification).</p></li>
<li class="listitem"><p>URI=""
identifies the node-set (minus any comment nodes) of the XML resource
containing the signature</p></li>
<li class="listitem"><p>URI="<font><span class="type">chapter1</span></font>"
identifies a node-set containing the element with ID attribute value
'chapter1' of the XML resource containing the signature. XML Signature
(and its applications) modify this node-set to include the element plus
all descendents including namespaces and attributes -- but not comments.</p></li>

<p>If the data object is a node-set and the next transform requires octets,
the signature application MUST attempt to convert the node-set to an octet
stream using Canonical XML [XML-C14N].</p>
<p>The story is different if the right transform is base64 decode
(http://www.w3.org/TR/xmldsig-core/<font><span class="type">sec-Base-64</span></font>):</p>
<p>This transform requires an octet stream for input. If an XPath node-set
(or sufficiently functional alternative) is given as input, then it is
converted to an octet stream by performing operations logically equivalent
to 1) applying an XPath transform with expression self::<font><code class="function">text()</code></font>, then 2)
taking the string-value of the node-set. Thus, if an XML element is
identified by a barename XPointer in the Reference URI, and its content
consists solely of base64 encoded character data, then this transform
automatically strips away the start and end tags of the identified element
and any of its descendant elements as well as any descendant comments and
processing instructions. The output of this transform is an octet stream.</p>

<p>XSLT transform klass (http://www.w3.org/TR/xmldsig-core/<font><span class="type">sec-XSLT</span></font>):</p>
<p>The normative specification for XSL Transformations is [XSLT].
Specification of a namespace-qualified stylesheet element, which MUST be
the sole child of the Transform element, indicates that the specified style
sheet should be used. Whether this instantiates in-line processing of local
XSLT declarations within the resource is determined by the XSLT processing
model; the ordered application of multiple stylesheet may require multiple
Transforms. No special provision is made for the identification of a remote
stylesheet at a given URI because it can be communicated via an  xsl:include
or  xsl:import within the stylesheet child of the Transform.</p>
<p>This transform requires an octet stream as input. If the actual input is an
XPath node-set, then the signature application should attempt to convert it
to octets (apply Canonical XML]) as described in the Reference Processing
Model (section 4.3.3.2).]</p>
<p>The output of this transform is an octet stream. The processing rules for
the XSL style sheet or transform element are stated in the XSLT specification
[XSLT]. We RECOMMEND that XSLT transform authors use an output method of xml
for XML and HTML. As XSLT implementations do not produce consistent
serializations of their output, we further RECOMMEND inserting a transform
after the XSLT transform to canonicalize the output. These steps will help
to ensure interoperability of the resulting signatures among applications
that support the XSLT transform. Note that if the output is actually HTML,
then the result of these steps is logically equivalent [XHTML].</p>

<p>The "remove xml tags" transform klass (http://www.w3.org/TR/xmldsig-core/<font><span class="type">sec-Base-64</span></font>):
Base64 transform requires an octet stream for input. If an XPath node-set
(or sufficiently functional alternative) is given as input, then it is
converted to an octet stream by performing operations logically equivalent
to 1) applying an XPath transform with expression self::<font><code class="function">text()</code></font>, then 2)
taking the string-value of the node-set. Thus, if an XML element is
identified by a barename XPointer in the Reference URI, and its content
consists solely of base64 encoded character data, then this transform
automatically strips away the start and end tags of the identified element
and any of its descendant elements as well as any descendant comments and
processing instructions. The output of this transform is an octet stream.</p>

<p>Selects node subtree by given node id string. The only reason why we need this
is Visa3D protocol. It doesn't follow XML/XPointer/XMLDSig specs and allows
invalid XPointer expressions in the URI attribute. Since we couldn't evaluate
such expressions thru XPath/XPointer engine, we need to have this hack here.</p>
